[Endovascular treatment of acute iliofemoral deep venous thrombosis - our results with catheter-directed thrombolysis and AngioJet]. / Az akut proximális mélyvénás thrombosis endovascularis kezelése ­ a lokális katéteres lysissel és az AngioJet-tel szerzett tapasztalataink.

INTRODUCTION: Most of the patients with iliofemoral thrombosis treated with anticoagulants only are affected with postthrombotic syndrome (PTS) that worsens the patients' quality of life. In the acute phase of proximal deep venous thrombosis (DVT) catheter-directed (CDT) and pharmacomechanical thrombolysis may be a reasonable alternative therapeutic method. Our aim was to summarize our results using these methods. METHODS: Since 2009 twenty-four patients with iliofemoral DVT were treated with these endovascular procedures and with stenting at our Institution. RESULTS: The median age of the patients was 35.83 ± 15.9 years, the female: male ratio was approximately 2:1. The mean time between the onset of the symptoms and the procedures was eleven days. CDT alone was performed in 8 patients, thrombus aspiration in addition to CDT using AngioJet device in 16 patients; in 19 cases the procedure was completed with venous stenting. During the follow-up we performed US examinations and estimated the severity of PTS by Villalta-scale. The total recanalization-rate was more than 50%, which even improved during the follow-up. The total lysis time and the amount of used recombinant tissue plasminogen activator decreased significantly by applying the AngioJet. We did not find any severe PTS among our patients during the follow-up visits. CONCLUSION: Our data suggests that these methods can be used efficiently and safely in the treatment of acute iliofemoral DVT.

[A rare cause of ilio-femoral deep vein thrombosis in young adults: asymptomatic chronic inferior vena cava occlusion]. / Fiatalkori iliofemoralis mélyvénás thrombosis ritka oka: tünetmentes vena cava inferior elzáródás.

INTRODUCTION: Acute lower extremity deep venous thrombosis in young adults is usually related to thrombophilia, immobility, trauma, surgery or malignancy. Therapeutic options have recently included pharmacomechanical thrombus removal although there is no evidence of the indication or of the long-term benefit. Rarely unknown, asymptomatic chronic neonatal inferior vena cava occlusion could also lead to acute ilio-femoral thrombosis. AIM: The aim of the authors was to present the therapeutic possibilities in lower extremity deep venous thrombosis connected with chronic inferior vena cava occlusion. METHOD: In a retrospective single center study data of 21 adults were analyzed. RESULTS: In 4 of the 21 patients chronic inferior vena cava obstruction was identified as an underlying cause of the acute thrombosis. Pharmacomechanical lysis was not offered to them and anticoagulation therapy was introduced. After an average 27.5 ± 11 month follow-up all the patients were alive and no adverse event occurred. CONCLUSIONS: In patients with acute lower extremity deep venous thrombosis and chronic inferior vena cava occlusion the indication of the endovenous pharmacomechanical lysis therapy is questionable. The authors suggest to consider computed tomography angiography or magnetic resonance angiography in addition to duplex sonography in patients with no obvious risk factors for lower extremity deep venous thrombosis to avoid unnecessary invasive treatment.
